Versuchsvorschrift
As for Example 6, 3-(2-quinolylcarbonyl)propionic acid (0.01 mole) is coupled to L-proline (0.011 mole) with 1,1'-carbonyldiimidazole (0.01 mole) in tetrahydrofuran to give 1-[3-(2-quinolylcarbonyl)propionyl]-L-proline. Bromination of the preceding compound and reaction of the resulting compound with sodium thioacetate gives the product of the Example.
